BAZOR-BLAlDE HOLDER.

Application filed June 3, 1921. Serial No. 474,666.

Tooll who'm it may concern:

Be it known that I, HERMAN L. Pn'rnit son, a citizen of thefUnited States, residing at Rockfordfiini th'e'cou-nty of Winnebago and State of lllinoisyhave invented certain new and useful Improvements in Razor- Blade Holders, of which the following is a specification.

This invention relates to holders for safety razor blades, and has more particular reference to that class adapted for bold ing straightedge blades during honing and sh arpenin g operations.

Many different forms of safety razor blade holders have been devised, but so far as Iain awarenone have been so constructed as to permit-honing a blade after the fashion of and with the same hand motion as when honing an ordinary razor. and with the blade maintained at a predetermined angle with respect to the abrasive surface without causing undue filling of such surface as a result of the holder body contacting the snrface throughout a substantial length. The primary object of the present invention, therefore, is to provide a razor blade holder which may be used either for honing on a flat stone or suitable abrasive surface in movements similating the honing of an ordinary razor. and in which the holder has only a. ball point contact with the stone, and through such contact determines the angle of the blade with respect to the stone.

In furtherance of this general object, I have provided a holder characterized by a handle equipped with blade-holding means and carryingbeyond the outer end of the "blade. a suitable roller or ball adapted to roll on a. surface amociated with the abrasive surface for determining the angle of a blade with respect thereto.

Another important object of my invention is to provide a razor blade holder oft-he character described. that is, including a roller or ball at the outer end of the blade in which the'b'lade is adapted to be automate cally reversed through action of the roller member upon reversing the stroke.

A further object is to provide a holder of simple and novel design embodying such characteristics as to permit the holding of practically any straight-edge safety razor blade. 1

A still further object resides in the provision of a razor blade holder so designed that it will be practical and ellicient for the purposes in mind and will consist of few parts' so designed as to permit production at a comparatively low cost.

Other objects and attendant advantages ll be appreciated by those familiar with this art as the invention becomes better understood by reference to the following description when considered in connection with the accompanying drawings, in Which Figure 1 is a side view of a razor blade holder embodying one form of my invention;

through the holder taken substantially on the line 2-2 of Fig. 1;

Fig. 3, a similar sectional view showing the blade-clamping means in the position with the blade removed;

Fig. 4, an end view of the handle;

Fig. 5. a side view partly in section of a razor blade holder enibodyin another form of my invention, showing it iii a bladeholding position;

Fig. 6. a view looking at another side of the holder shown in Fig. 5, but with the bladeclamping members in a non-clamping position;

Fig. 7, a fragmentary view showing the blade holder in condition for stropping;

Fig. 8. a section taken on the line 8-8 of Fig 4 and ig; 9. a view of the holder showing its use on a hone.

In one form of my invention shown in Figs. 1 to 4 inclusive. the blade may be honed and stropped after the fashion of an ordinary razor. In this form. the blade 12 is clamped between spring members 13 and 14, which in the present instance, are made from a single piece of material bent medially upon itself so that the ends 13 and 14 are in abutting relation. These clamping members carried by a handle 15, are-so mounted thereon as to be capable of lengthwise movementwith respect thereto for the purpose of clamping and releasing a blade. To. this end, the members 13 and 14 are slidable lengthwise in a groove or socket 16 in the handle and pass through a. bushing 17' carried by the end collar 18 which is fixed to the handle,

As sho vn plainly in Fig. 2, the member 13 is considerably longer than the member 1- which has a laterally turned end 19 adapted to abut agginst the inner endeli-t lipbn ihigg 17 for limitin outward mov mflih f tire clamping member. lVhen the members are in their outermost l osit-iOn the member. 4;.

will spring open as shown in Fig. 6, per

mitting the insertion of a safety ramnblade seourely held in the holder. It will e noted that in the present construction, the outer end portions ofihe members 13 andilit are held age-instseparationby a clip 21, andthat. the'end portions 22 are bulged outwardly and'bored or shapedto'pronide ball-retnifling openings 23. A steel ball 24 of greater diameter than said holes 23 is, interposed between the: outer end'portions 22 soasto be retained thereby and projectrthrough the openings 2%: This ball, free to rotate in its retainenisthe only part of the holder which contacts the face of thestone or a-braSia -e surfer-e- It follows that when the holder is moved'liaok andfm'th OI -in oirenlar or any desired movement over the stone; thev hall maintains the blade at apredetermined anpie with respect to the stone by rolling the-reon and there is practically no ebrasi ve ae tion between the holder proper and the stone. This will be obvious from the fact that the handle is held in one hand with the ball resting on the stone andthe blade inclined with its enttingiedge flat againstathe stone. similar to the position shownin Fig. 9. To remove the blade it is only necessary to pull the members 13-14 outwardly of the handle to a position limited by the stop 19, in Which therpart 14 is free tospringopen, thereby releasing the blade.

In Figs. 5' to 9 inclusive, I have shown another embodiment. of my invention in which the blade holder is adapted tobe used for honing alone. or as in the former in stance, either for honing or stroppiugw In this embodiment, the handle Qi'iea-I'ries a. shank 26 in the form of a rod, upon whieh is mountedton swinging movement A about the axis of themed, a blside holder ooln prisingspning members 27 28. These niennbersattached together st 29:, arepivotially connected to the rod 26ithreitgh the agencyjofi a band 3t and tihe sl'i'dnble sleeve. '32; each of which embraces. the; red. the.

sleeve 32 also closely embvaeing theelampr ing members. By interposing a blade be tween said clamping members and sliding the sleeve 32 toward the blade, the lat tvr will be stamped. by ondilm {$2 k i i lj bers- It will now be obsers'ed that the hlflde holder is equipped at its outer end with a ba ll 33.nfhi0h is seated between the part 31 and'zin expansion spring 34. In honing, the blade isgositioned on a stone as shorrn in Fig. 9, and with the ball resting on the stone the. holden wtilli be moved to the left. At. the end of the stroke the movement Will be reversed, thereby reversing rotation ot the ball, which being urged against the blade holder by the spring34. willinstantly rererse the posit'ion of such holder, thaitiis. cause the same to move by frictional Contact; with the ball to the position. shown in.-

dotted lines, Fig. 9, whereupon the ball will:

continue to roll as the spring pressure is not 'sufi'cient to overcome the frictional vontactof the ballion the stone. Thusais the holder: is moved back and torththe-blnde will be automatically reversed at the end of eaeh stroke and by the same means which do: termines the working angle ofthe cntitiing edge. ln the event. that, it is. desired touse this form. of holder for; strop aing on for honing in. the. manner first describedabove, thosleere iidwhich is slidableiointhe shank; rfloket 3.6 and is Shaipedfiio embracetheex; tended end 37. of F the. lamping member 8.; will be moved: fioriweedly on said shank braek t to the position shown in Fig. 7 to engage said end 37. In this manner the blade clamping members will be lea-lied against rotation on the rodi26;and the blade will be held rigidrwith respect to the holden handle.

To remo ea. blade the. sleeves 32 will slid back to the dotted, line position shown in Figv 5, thus releasing the shorter clamping member 28. which wil'lrspringopen as shown inFigr. .6, releasingthe blade.
